摘要

摘要: 针对单向阀开启过程中强迫振动产生的根源和流激振动问题，构建了开度为5%、15%、30%、50%、75%和100%的流固耦合仿真模型，对不同开度情况下的流体与固体场特性以及流体施加于阀芯上的流激振力进行数值分析，得到了流场压力云图、速度矢量云图和流激振力脉动峰值频率以及阀芯在各开度下的模态振型和固有频率。结果表明：单向阀开启过程中，阀芯两侧存在较大的压差，变形区域主要集中于胶垫，阀腔内高速流体与低速流体接触时出现剪切形成涡流，流动涡流周期性变化产生的流激振力导致阀芯被迫振动，阀芯上的流激振力脉动峰值频率分布范围逐渐增加且波动更大。

Abstract: Aiming at the root causes of forced vibration and flow-induced vibration problems during the opening process of the check valve, a fluid-structure interaction simulation model with different opening degrees of 5%, 15%, 30%, 50%, 75% and 100% was constructed. The characteristics of the fluid and solid fields and the flow-exciting force exerted by the fluid on the valve spool were numerically analyzed, and the pressure cloud map of the flow field, the velocity vector cloud map, the peak frequency of the flow-induced vibration force, and mode shapes and natural frequencies of the valve core at each opening degree were obtained. The results show that: during the opening process of the check valve, there is a large pressure difference on both sides of the valve core, and the deformation area is mainly concentrated in the rubber pad. When the high-speed fluid in the valve cavity contacts the low-speed fluid, a vortex is formed by shearing, and the flow vortex changes periodically. The flow-exciting force generated by the vortex causes the spool vibration, and the peak frequency distribution of the flow-exciting force pulsation on the spool gradually increases and fluctuates more.
